A wye, in the context of HVAC (heating, ventilation, and air conditioning) systems, is a type of duct fitting that allows for a branch to be made in a duct run to a smaller size. It is called a "wye" because it resembles the letter Y in shape, with one larger inlet side and two smaller outlet sides branching off at an angle of 45 or 60 degrees. Wyes are commonly used in HVAC systems to branch off duct runs to supply air to multiple locations or to redirect airflow to different parts of a building.
Wyes from The Duct Shop are the perfect fitting to use when you need to branch off your duct run to a smaller size. The sizes are listed for the inlet side, the discharge side and then the branch side. All wyes are manufactured from the highest quality galvanized steel. They are perfect fittings for maintaining maximum airflow through your system while branching off to multiple locations.
HVAC Installation Tip — We recommend that you seal the seams with a duct sealant after installation to prevent any air leakage, increase the efficiency of your system and reduce your utility bills. See installation tip for Flexible Duct or Sheet Metal Duct, depending on which type you will be attaching to.
